Heat dissipation structure of transformer

Abstract

A heat dissipation structure of transformer includes a bobbin formed with a hollow shape and wound with a primary coil and a secondary coil. A core surrounds an inside and an outside of the bobbin by combining a pair of upper cores with a pair of lower cores. A heat dissipating plate is disposed between the pair of upper cores and the pair of lower cores. According to an exemplary embodiment of the present disclosure, heat generated inside of the core can be effectively exhausted outside by a heat dissipating plate disposed in the center of the core.

More particularly, the present disclosure relates to a novel heat dissipation structure of a transformer for dissipating heat generated from a core of the transformer. Background technique [0004] A transformer is a device that converts AC voltage or AC current by using electromagnetic induction. A general transformer includes a bobbin wound primary coil, a secondary coil, and a core formed of a magnetic material so as to surround the inside and outside of the bobbin. The transformer further includes semiconductor switching components such as field effect transistors (FETs), insulated gate bipo...
